Description

Twisting machine's winding drum and feed roller driving mechanism}

The present invention relates to a winding drum and a feed roller driving device of the twisting machine, and more particularly, the driving of the winding drum and the feed roller is made by a driving structure that is configured separately. The present invention relates to a winding drum and a feed roller driving device of a twisting machine designed to drastically reduce manufacturing costs and maintenance costs according to the operation of the twisting machine.

Conventional twister is a single drive motor (M) to drive the spindle, the winding drum and the feed roller and the slide operation of the traverse bar, the conventional drive device for driving the winding drum, feed roller and traverse bar (1 As shown in FIG. 1, the gear housing 2 is provided by providing a gear housing 2 on an upper portion of the drive pulley 3 that receives power from the driving motor M of the twisting machine by means of a belt B or the like. Several drive gears 4 driven by the pulley shaft are engaged with each other so that the winding drum shaft 20 and the feed roller shaft 21 are driven by the respective drive gears 4 and in the gear housing 2. The drive cam (5) actuated by the drive gear (4) is installed so that the traverse bar (6) slides forward and backward.

The above-described conventional drive device 1 is considerably complicated in structure and therefore requires a large amount of time for production, and requires several components such as drive gear 4 and drive cam 5. The cost required was high, and since the drive device 1 is configured to receive power from the drive motor M for driving the spindle 7 (see Fig. 2), a drive motor having considerable power is required for the manufacture of the twisting machine. There was a problem such as that, such a problem has not only acted as a major factor to increase the manufacturing cost of the twisting machine, but also has a problem such as a high cost of electricity (electricity charge) due to the operation of the twisting machine.

Substantially, the conventional twister uses a 30-horsepower drive motor (M) to drive the winding drum and feed roller and slide the traverse bar together with the spindle drive, which uses a 30-horsepower drive motor (M). If you operate 30 days for 24 hours a day, the electric charge for each projector will be 600,000 won.

In addition, the conventional drive device (1) has to be replaced with a drive gear (4) having different specifications according to the desired number of revolutions when adjusting the rotational speed of the winding drum and the feed roller. There have been closures such as a large amount of time lost due to the replacement of the drive gear 4.

The present invention was created to eliminate all the problems of the conventional drive device as described above, so that the winding drum and the feed roller can be driven by a simple drive structure separately configured to significantly reduce the manufacturing cost of the twisting machine and the maintenance cost according to the operation of the twisting machine. The winding drum and feed roller driving device of the completed twister with the main focus of the technical problem is to improve the convenience of use of the twisting machine by allowing the user to conveniently reduce the rotational speed of the winding drum and the feed roller. to provide

2 to 3 shows a preferred embodiment of the drive device 10 presented in the present invention, as shown in the present invention is a geared motor (M) of the control of the rotational speed by the controller (C) The driving shaft M1 and the first driving shaft 11 are connected to each other by power transmission means such as the timing belt 19 and the belt pulley 13, and the first driving gear G1 is mounted on the first driving shaft 11. Install.

The second drive gear G2 is axially installed on the second drive shaft 12 arranged in parallel with the first drive shaft 11, and meshes with the first drive gear G1 installed on the first drive shaft 11. By driving the geared motor (M) so that the first drive shaft 11 and the second drive shaft 12 is driven in the opposite direction to each other.

The first and second drive shafts 11 and 12 and the first and second winding drum shafts 15 and 16 are connected to each other by power transmission means such as a belt pulley 13 and a timing belt 19. The first and second drive shafts 11 and 12 are connected by connecting the drum shafts 15 and 16 and the first and second feed roller shafts 20 and 21 with power transmission means such as the belt pulley 13 and the timing belt 19. The first and second winding drum shafts 15 and 16 and the first and second feed roller shafts 20 and 21 may be driven by driving of the first and second winding drum shafts 15 and 16.

On the other hand, in the above embodiment, the first and second winding drums transmit the driving force of the driving shaft M1 to the first driving shaft 11 and the driving force of the first driving shaft 11 and the second driving shaft 12. Power transmission means for transmitting to the shaft (15, 16) and the drive force for transmitting the driving force of the first and second winding drum shaft (15, 16) to the first and second feed roller shaft (20, 21) belt Using a means such as the pulley 13 and the timing belt 19, and to enable the accurate transmission of the driving force and the configuration has been described to minimize the mechanical noise, the power transmission means as described above more accurate driving force It can be replaced by a power transmission means such as a chain sprocket and a chain for the transmission of the, of course, the substitution of the power transmission element as described above is only a simple design change that can be made by the technical idea enjoyed by the present invention on A detailed description of the description is omitted.

According to the present invention having the above configuration, the rotational speed of the geared motor M is controlled by the operation of the controller C. The first drive shaft 11 and the second drive shaft 12 are driven by the geared motor M. FIG. The winding drum 23 pivotally mounted on the first and second winding drum shafts 15 and 16 connected simultaneously with the first and second drive shafts 11 and 12 and the power transmission means rotates in the opposite direction, and the first and second windings rotate. The feed rollers 22 axially installed on the drum shafts 15 and 16 and the feed roller shafts 20 and 21 connected by the power transmission means rotate.

On the other hand, in some cases, a rotational speed that exceeds the adjustment range of the rotational speed by the geared motor (G) may be required. In such a case, the rotational speed is replaced by a belt pulley (or chain sprocket) having a different specification. (By self testing, three types of belt pulleys (or chain sprockets) with different specifications were used to control all the rotational speeds required by a conventional twister.)

As described above, the winding drum and the feed roller driving device 10 of the twisting machine presented in the present invention engage the first and second driving shafts 11 and 12 with the first and second driving gears G1 and G2. The feed roller 22 and the winding drum 23 can be driven simultaneously by a simple structure in which the two driving shafts 11 and 12 and the first and second guiding drum shafts 15 and 16 are connected by a power transmission means. The manufacturing cost of the twisting machine can be reduced, and the operating speed of the twisting machine can be improved by allowing the geared motor M to freely adjust the driving speed of the feed roller 22 and the winding drum 23. There is.

In addition, the present invention allows the feed roller 22 and the winding drum 23 to be driven by a drive structure configured separately to increase the capacity of the main drive motor (motor for rotating each spindle of the twisting machine) used in the twisting machine. It was able to lower 7.5 horsepower from the conventional 30 horsepower, and as the capacity of the driving motor was reduced, it was possible to reduce the maintenance cost (electricity) according to the operation of the injector by about 1/3 compared with the conventional injector. The effect is indeed a very good design.
